STAPLE FORMING AND DISGI-IARGING MECHANISM.

season To all whom it may concern:

Be it known that I, VERNON HOXIE, a citizen of the United States, and aresident of Adrian, in the county of Lenawee and State of Michigan, haveinvented a certain new and useful Staple Forming and DischargingMechanism; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which itappcrtains to make and use the same,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification.

My invention relates to mechanism of the class which is particularlyapplicable for use in conjunction with machines for the weaving of wirefabric to sever sections of wire intermittently fed thereto, form thesame into staples and then to discharge the formed staples from suchmechanism and clamp them about intersecting wires of the fabric.

The object of my invention is the provision of improved mechanism ofthis class, which is simple and efficient in its operation, cheap ofmanufacture and strong and durable in its construction.

The operation, construction and arrangement of the parts of theinvention are fully described in the following specification, and twoembodiments thereof illustrated in the accompanying drawings, in whichFigure 1 is a front elevation of a mech anism comprising my invention.Fig. 2 is a side elevation of the same with portions broken away. Figs.8 and 4t are similar views, respectively of a modified form of theinvention. Fig. 5 is a section on the line :0 00 in Fig. 2. Fig. 6 is aplan view of Fig. 4t, and F ig. 7 is a perspective view of thestripper-block employed in the modified form.

Referring to Figs. 1, 2 and 5 of the drawings, 1 designates the baseblock or holder, which has its top preferably inclined, as shown, andfaced with the two transversely spaced top-plates or bars 2, 2, whichhave their inner or contiguous sides longitudinally grooved, as at 3, toform a guide-way for the staple-discharging and clamping plunger 4 and adischarge-way for the formed staples. The plunger 4: has its lowerportion working in a registeringgroove or cored portion of the holder 1,and

may have reciprocatory movements communicated thereto from areciprocatory table or block 5 through the medium of a link 6, saidtable being actuated in any suitable manner. Rising from the forwardportions of the top-plates 2, 2 is the staple forming anvil 7, which hasthe broadened foot 8 at its lower forward edge for bolting to saidplates. This anvil is of narrow construction 4 to permit the formedstaples to slide down the same, and has its lower rear portion projecteddown within a cut away portion 9 of the top plates to near the top ofthe grooves at substantially a rightangle thereto to guide the staplesfrom forming to discharging position. The formed staples are held to theslide or anvil '2' by a backing-block 10, which rises from the topplates2, 2 at the rear of and in slightly spaced relation to the rear edge ofthe anvil. The wire a from which the staple sections are severed isintermittently fed by any suitable mechanism, to the rear of the upperend of the anvil 7 in the path of movement of a pair of formers ll, 11through an aper tured die 12, which is carried at the upper end of anarm 13, rising from one side of the holder 1, as shown. The formers 11,11 project radially from the sides of a disk or wheel 14; and areadapted, when revolved by a turning of the disk 14, to pass on oppoonopposite sides of the fed lengths of wire to guide the same to formingposition. The formers 11, 11 are permitted to pass by a staple afterforming the same around the anvil 7, due to the provision of grooves 18,18 (Fig. 1) in the inner faces of the formers 11, 11 through which thelegs of the staples pass. 19 designates a cutter-plate, which isdisposed at the side of the former 11, which is contiguous to the arm13, and is intended to cooperate with the inner end of the die 12 l tosever the fed wire section from its thread at approximately the instantof contact of the formers therewith. This cutter-plate is shown as beingcarried for radial adjust-.

ment relative to the disk 14: by the securing bolt 20 passing through alongitudinal slot 21 in said plate. Shoulders 22, 22 coact with thesides of the cutter-plate to prevent a turning thereof relative to thedisk 14. The operation of this form of my invention is as follows :-Ateach revolution of the disk lt a section of wire is fed to the formingpart-s through the die 12, is severed by the shearing contact of theknife 19 with the inner end of such die, and is then formed into astaple around the anvil 7 due to the action thereon of the formers ll,11. The formed staple, when freed by the formers passing out of contacttherewith, drops by gravity down the slide formed by the anvil 7 andrests on top of the staples carried thereby, being held in place by thebackingblock 1.0. W hen the plunger lis at the limit of its rearwardthrow, the forward end of its discharge nose has receded from under thestaple column held by the slide 7, thus permitting the lower one of suchstaples to drop into the discharge-way 3 in advance of the plunger nose,as shown in Fig. 2. On the forward stroke of the plunger this staple isdischarged from the holder and clamped about the registeringintersecting portions of the fabric being woven. The movement of theparts is so timed that the disk 14 makes one revolution to a forward andback movement of the plunger.

In the modification illustrated in Figs. 3, l, 6 and 7, 23 designatesthe holder or base block; 24L the top-plate having the stapledischargeway 25 therein; 26 the plunger working in said way; 27 the linkconnecting the plunger with the actuating table 28; 29 the anvil, whichrises from the forward end of the top-plate 24 and has its lower rearportion angled rearwardly at approximately a right angle to thedischarge-way 25 and projected down through a cutaway portion 30 (Fig.3) of the top-plate to a 'point immediately above the plane of movementof the plunger, and 31 the arm which rises from the side of the holder23 and carries the apertured die 32 at its upper end through which thewire a feeds to the forming parts. 33, 33 designate two oscillatoryformerarms, which are pivotally carried at opposite sides of the anvil29 by a bolt or pin 3a passing through their upper ends and the upperend of said anvil, and each is pivoted near its lower end to an arm ofthe forward forked end of the link 35, which connects at its rear end toa boss 36 rising from the plunger 26. A cutter-block 37 is secured tothe side of the arm 33, which is contiguous to the arm 31., and isintended, on each for ward movement of the arms 33, to coact with theinner end of the die 32 to sever the fed section of wire. The severedsections are guided to the grooves 38 in the inner sides of the arms 33by the forwardly projecting fingers 39 and on the continued forwardmovements of said arms they act on the severed sections to form theminto staples around the anvil 29. On the receding or rearward movementsof the former-arms 33 the formed staples are freed therefrom by a block40, which is secured to the top-plate 24- at the rear of and in slightlyspaced relation to the anvil 29 and has a stripper-part ll risingbetween the paths of movements of the former-arms. In the operation ofthis form of my invention it is apparent that at each forward stroke ofthe plunger 26 a staple is discharged from the discharge-way 25, andthat the forward movement of the arms 33, 33 by the plunger effects asevering of a section of wire and a forming of the same in staple-formaround the anvil 29. On the rearward movement of the formerarms theformed staple is stripped therefrom by the stripper-part 40 and is thenpermitted to drop by gravity to rest on the top of the staples carriedby the anvil. The feeding of the wire is timed to take place when theplunger is at the rear portion of its movements.

I wish it to be understood that my invention is not limited to anyspecific construction or arrangement of the parts except in so far assuch limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-
